TMDS361B - Low power state and HPD status

Guru 19785 points
Other Parts Discussed in Thread: TMDS361B

Hello Team,

Could you please help us support TMDS361B ?

Our customer is evaluating the operation of TMDS361B, however, there is no signal from source side even when sink side system is connected. One thing we found was that /LP pin (Pin 49) were connected Low in their schematic. They uses the device in I2C mode. Here are some questions we have.

[Q1]
When used in I2C mode (I2C_SEL pin = Low), is the /LP pin setting ignored ? What happens when /LP pin is connected to GND, always in low power state ?

[Q2]
What is the status of HPD1/2/3 and HPD_sink pins in low power state ? Are the HPD1/2/3 pins and HPD_Sink pin disconnected ?


Best Regards,
Kawai
